When testing the response of many pulse-width-modulated (PWM) systems, there's a need to independently vary a multivibrator's frequency and duty cycle. Such systems include dc motors, ultrasonic ...
A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...
The LM3495 PWM buck controller from National Semiconductor employs the company's emulated-current-mode architecture to generate output voltages with very low duty cycles at switching frequencies up to ...
The duty cycle is the ratio of the turn-on time (TON) to the complete cycle length, the turn-off time (TOFF) plus on time, and defines a simple relationship between the input voltage and an output ...
High-performance motion control demands compact and economical servomotors. Fortunately, because most servo applications only intermittently demand maximum continuous-torque motor output, a smaller ...
